Automated, percutaneous biopsy device.
An automated, percutaneous biopsy device was developed. A miniaturized motor in a 20-mL syringe produces low-speed rotation of the distal helical stylet for tissue acquisition. The device was used in vitro in 30 lesions, and the samples demonstrated adequate preservation of cell structure. In lesions with fibrous, calcified, or osseous components, the device was superior to conventional needles. The device has also been successfully used in 10 patients.
